WorldCat Discovery Services

Connect your users to the information they need.
Connect your library to the world.

Uniquely valued by member libraries, FirstSearch will continue to be offered as a separate service.

OCLC continues to enhance WorldCat Discovery with features from WorldCat Local and features requested by the WorldCat Discovery community.

In addition to ongoing WorldCat Discovery enhancements, OCLC will continue the full-featured WorldCat searching valued in FirstSearch in a new version of FirstSearch.  WorldCat Discovery and the new version of FirstSearch will continue as separate services, and FirstSearch search features will also be available to WorldCat Discovery users.  WorldCat Discovery remains the user-facing interface to WorldShare Management Services.

As OCLC works to deliver critical functionality to both WorldCat Discovery and the new version of FirstSearch, access to the current version of FirstSearch will extend beyond the 2016 calendar year into 2017.

Additional details about plans to enhance WorldCat Discovery and release the new version of FirstSearch will be shared as they are confirmed.  To receive ongoing updates about enhancements to the WorldCat Discovery service, register for Discovery and Reference email updates.
